Most people call because they have a space that needs a floor, like a new addition or a shop, or an old slab that has cracked, sunk or gone uneven and has to come out. D&R Auburn Concrete is based in Auburn, and we do this work here and in the cities around it, including Kent, Renton, Federal Way, Tacoma and Lake Tapps.
The price moves first with the size of the floor in square feet. After that it depends on whether old concrete has to come out, how much digging and packing the base needs, whether the slab gets rebar and how easily concrete reaches the spot. Your own figure comes in the written estimate I give you after I've seen the space.
The schedule turns on the weather on pour day and on any permit. Most of all, it turns on what goes on top, because a slab under flooring has to dry well past the day you can walk on it. A floor that stays bare is in use much sooner.
